mKgIY.jpg (588×441) This is a news website article about a scientific finding. In this paragraph I will state the main claim that the research makes, making appropriate use of "scare quotes" to ensure that it's clear that I have no opinion about this research whatsoever.
In this paragraph I will briefly (because no paragraph should be more than one line) state which existing scientific ideas this new research "challenges". If the research is about a potential cure, or a solution to a problem, this paragraph will describe how it will raise hopes for a group of sufferers or victims.
